v0.1.0

• Storage moved to a single SQLite database (cashctl.db), replacing three JSON files.
• transfer --amount picks which held token(s) to use, auto-consolidating same-minter tokens when none alone covers it.
• receive accepts NIP-CASH bearer gift-strings (<token>#<bearer_secret>) and auto-secures bearer receipts.
• decode/redeem/transfer/consolidate warn before an action that would fail on an expired token.
• redeem accounts for the Hub's redeem fee; --to renamed to --into.
• nconnection1... targets and NIP-05 identifiers are supported and validated before use.
• Fixed several bugs: a lost update on concurrent saves, a bearer-target transfer that discarded its own secret, a secret leak in --json output, and a duplicate-receive race.
• Wire text from a Hub/wallet is sanitized before printing; error messages are more specific and less generic.
• Circle hub fee terms and forwarding-fee skim are now visible in wallet get-info/wallet pay.
